Freezing Point of isopropyl alcohol
Purpose: Is it possible to get isopropyl alcohol to
freeze above 5, 000 ft. elevation
Prior Knowledge:
Isopropyl alcohol (C3H8O.)
Melting point
−89 °C, 184 K, -128 °F
Boiling point
82.5 °C, 356 K, 181 °F
Hypothesis:
If isopropyl alcohol is placed in a test tube,
Then continually surrounded by ice,
When the ice is stirred, the isopropyl alcohol
will / will not reach its freezing point
temperature.
Materials:
1 test tube
1 beaker
10 ml isopropyl alcohol
Ice
Thermometer
